Keep those WUs in the queue. As soon as your assigned server is back on line, they will be accepted. Might be worth a close of the program and restart each morning, if you are running 24/7. The F@H program has log files (plain text) that note your start/finish date, and you should get full credit when submitted. Had some WUs languish for several days, then accepted. I do not run 24/7. Electricity costs more than $0.175 per KWH (USD) by me!
